YuvImage

YuvImage contains YUV data and provides a method that compresses a region of the YUV data to a Jpeg. The YUV data should be provided as a single byte array irrespective of the number of image planes in it. Currently only ImageFormat.NV21 and ImageFormat.YUY2 are supported. To compress a rectangle region in the YUV data, users have to specify the region by left, top, width and height. Requires API level 8 (Android 2.2, Froyo)

ByteArray!: (Optional) Row bytes of each image plane. If yuv contains padding, the stride of each image must be provided. If strides is null, the method assumes no padding and derives the row bytes by format and width itself.
